Verify an incoming call

Make sure that an incoming call from the SIP network enters correctly context CS. The following sequence
shows a working call setup.
unit(cfg)#debug gateway sip error
unit(cfg)#debug gateway sip transport
unit(cfg)#18:53:40
18:53:40 SIP_TR> Sent SIP/2.0 100 Trying
18:53:40 SIP_TR> Sent SIP/2.0 180 Ringing
18:53:43 SIP_TR> Sent SIP/2.0 200 OK
18:53:43 SIP_TR> Received ACK sip:50@172.16.32.32:5060 SIP/2.0
Explanation:
• The line
18:53:40 SIP_TR> Received INVITE sip:50@172.16.32.32 SIP/2.0
message has been received. This means that the SIP network is functional
•
18:53:40 SIP_TR > Sent SIP/2.0 100 Trying
cate that responses are sent back to the SIP network. This means that the call routing is working correctly,
and the call has found its destination on the gateway that is debugged. If there are no responses, or a nega-
tive response, continue debugging call routing and the destination protocol.

Verify an outgoing call

Make sure that an outgoing call from context CS leaves correctly to the SIP network. The following sequence
shows a working call setup.
unit(cfg)#debug gateway sip error
unit(cfg)#debug gateway sip transport
unit(cfg)#18:59:07 SIP_TR> Sent INVITE sip:60@172.16.32.33 SIP/2.0
18:59:07 SIP_TR> Received SIP/2.0 100 Trying
18:59:07 SIP_TR> Received SIP/2.0 180 Ringing
18:59:10 SIP_TR> Received SIP/2.0 200 OK
18:59:10 SIP_TR> Sent ACK sip:60@172.16.32.33:5060 SIP/2.0
